4900 year old trees



This picture shows a row of disrupted cells in a tree ring from a bristlecone pine (Pinus longaeva) growing in the White Mountains of California (photo © R.K. Adams and H.D. Grissino-Mayer). This is no ordinary frost ring. This one was formed in the year 1627 B.C., and is connected with the eruption of Thera in the Mediterranean Sea.
